Light-triggered reversible "one-to-two" morphological transition in a "latent double-amphiphilic" linear-hyperbranched supramolecular block copolymer.

This study reports a new category of stimuli-responsive morphological transitions, i.e., from one morphology (e.g., vesicles) to another two different ones (e.g., nanosheets and nanofibers), by investigating the light-responsive self-assembly behaviour of a "latent double-amphiphilic" linear-hyperbranched supramolecular block copolymer.
